Snooker ace Ronnie O'Sullivan will receive an OBE from the Prince of Wales at Buckingham Palace on Friday.
The 40-year-old five-time world champion, who is also known as The Rocket, is being recognised for his services to snooker since turning professional in 1992.
David Cameron's general election campaign director, Lynton Crosby, who steered the Conservatives to victory last year, will also attend the ceremony.
Mr Crosby, originally from Australia, has also been running the London mayoral campaign for Tory candidate Zac Goldsmith and is receiving a knighthood for his political service.
But his decoration has not been without controversy, with shadow home secretary Andy Burnham condemning Mr Crosby's knighthood when it was announced.
"This outrageous award is the clearest evidence yet that the Tories think they can get away with whatever they like," he said.
"It is a timely reminder that Labour must make it a New Year's resolution to stop facing inwards and expose them for what they are."
Actress Sian Phillips will also be recognised at the investiture ceremony when she is made a dame for her services to drama.
The 82-year-old Welsh leading stage and screen star has, throughout her career, appeared in the 1969 musical film Goodbye, Mr Chips, as well as episodes of New Tricks, Midsomer Murders and Holby City.
